2. Known Problems and SolutionsThe following table provides the
list of known problems and solutions.
Table 2-1. Known Problems and Solutions
Problem Solution
Occasionally ATWINC15x0 fails to receive anindividual UDP
broadcast frame when inM2M_PS_DEEP_AUTOMATIC powersave mode.
Use M2M_NO_PS Power Save mode if reliability ispreferred for UDP
broadcast frames. Otherwiseensure the overlying protocol can handle
the oddmissing frame.
The ATWINC15x0 cannot handle two simultaneousTLS handshakes, due
to memory constraints.
When attempting to open two secure sockets inSTA mode, the
application should wait to benotified of the first one completing
(succeeding orfailing) before attempting the second one.
Under high interference and high data throughput(TCP/UDP), the
ATWINC15x0 occasionally runsout of memory for receiving data and
does notrecover. This occurred 4 times during 9 hours ofhigh
interference high throughput Rx/bidirectionaltesting.
Close all sockets then retry the data transfer.
1% of Enterprise conversations fail due to theATWINC15x0 not
sending an EAP response. Theresponse is prepared and ready to send
but doesnot appear on the air. After 10 seconds thefirmware
times-out the connection attempt and theapplication is notified of
the failure to connect.
Configure the authentication server to retry EAPrequests (with
interval < 10 seconds). Theapplication should retry the
connection requestwhen it is notified of the failure.
Using the m2m_wifi_set_tx_power() APIstops the ATWINC15x0 from
transmitting.
Avoid using the m2m_wifi_set_tx_power()API.
When connected to certain access points, theATWINC15x0 sometimes
fails to roam when theaccess point changes channel. The issue is
seenwith these access points: Linksys E2500, LinksysE4200, Linksys
6500. The failures to roam are dueto two issues:
• Sometimes the access point takes a longtime to start sending
beacons or proberesponses on the new channel, so it is
notdiscoverable.
• Sometimes the access point does not initiatethe 4-way
handshake (for WPA/WPA2 PSKreconnection).
On reception of M2M_WIFI_DISCONNECTEDevent, the application
should attempt to discoverthe access point
usingm2m_wifi_request_scan() API.
ATWINC15x0Known Problems and Solutions
© 2018 Microchip Technology Inc. Release Note 6251A-page 16
-
Problem Solution
When provisioning the ATWINC15x0 using amobile phone, 5% of
provisioning attempts causean error message “Request Failed” to pop
up onthe phone, even though the provisioning hassucceeded.
Ignore the “Request Failed” message.
When connecting to a TL-WR841N router, datatransfer is sometimes
unavailable until severalseconds after DHCP. Occasionally the
data-planeis never established.
If DHCP completes but data transfer fails,disconnect and
reconnect to the router.
If an AP uses an 802.11 ACK policy of “No Ack”,then the
ATWINC15x0 sometimes fails to receive802.11b frames.
Avoid using an ACK policy of “No Ack”. If “No Ack”is used,
ensure frames are sent at 802.11g orhigher rates.
70% of Enterprise connection requests fail with aTP Link Archer
D2 access point (TPLink-AC750-D2). The access point does not
forward the initialEAP Identity Re-sponse to the
authenticationserver. The issue is bypassed by PMKSA caching(WPA2
only), so reconnection attempts willsucceed.
The application should retry the connection requestwhen it is
notified of the failure.

Microchip Devices Code Protection Feature
Note the following details of the code protection feature on
Microchip devices:
• Microchip products meet the specification contained in their
particular Microchip Data Sheet.• Microchip believes that its
family of products is one of the most secure families of its kind
on the
market today, when used in the intended manner and under normal
conditions.• There are dishonest and possibly illegal methods used
to breach the code protection feature. All of
these methods, to our knowledge, require using the Microchip
products in a manner outside theoperating specifications contained
in Microchip’s Data Sheets. Most likely, the person doing so
isengaged in theft of intellectual property.
• Microchip is willing to work with the customer who is
concerned about the integrity of their code.
